Be it known-that I-,- KARL wm t; a Citizen .of i the. German Empire, residing in .1 Schwarzenberg, in 'the Kingdom ofSaxony,

filling att-achment for brush making. machines in which the mechanism'for impart-i ing' longitiidinal -rec1procatory and lateral.

This lever '5 is pro- 7 vlded with slots in its lower and upper ends,

and the slotted upper end is connected bv an intermediate pivot rod if with perforated ears i at the center of the rear portion of the table a; .The ends of the pivot rods 5 and 5* are adjustable in the slots of the lever *Fand by adjustment thereof the required length of stroke for imparting the desired The table a is made of sufiicient width for permitting two brush-backs or two sets' of brush-backs .to be supported thereon; which brush-backs are held'against a rear-flange a of the table by the clamping devices a which are adjusted from the front-edgeof table, These right and left'terms have refer- 55,

placed loosely on lateral rods '1 that are supported in eyes of yoke-shaped supports (1 shown clearly in Figs; 1 and 3. The rollers 'rare provided withcircumferential tapering flanges r onwhich the correspondingly-shaped ways of the table are guided with little friction. I

By the stroke-adjusting lever-mechanisms ---des c1-ibed,.oneand the same-pattern-wheel ,40

, nisms produce simultaneously the drilling of the hole in a brush-back supported at the left side of the machine and the insertion of a-tuft into a corresponding hole in a brushback clamped at the right-hand end of the ence to an 'op'eratorstanding at the left of Fig. '2 injfront of the machine andlooking towardiit. When two or more bluish-Jacks are to be drilled and filled a special pattern-wheel to has to be arrangechso as to permit the continuous working of the hole-drilling and -*tuft-filling mechanisms without requiring any interruptionof the machine." Then the left-hand brush-back or; backs are-drilled with the necessary number of socket-holes,

the table is shifted so that the boring tool can drill the holes in: the right-hand brushback or backs'adjacent thereto and the drillmg of the holes" continued-while the left-,

handbrush-back or brush-backs are exchanged and new brush-backs placed in position. Simultaneously the filling of the socket-holes of the brush-backs below the E tuft-filling inefhaiiism takes place the same rate, and when the left-hand brushbacks are filled the table is shifted so that the righthand brush-backs can be ed,'- the 1 filled left-hand brush-back or bri 1backs be ng then removed andfanether set of drilled brush-backs placelkin oos' on Ion the table while the filling of th rightland brush-backs is'continued, sufiici emb tin being available forproducing the one set of brush-backs and the lhmpi position-of another set onthe s ipper-ting 35" table, while the drilling and, filling of the other set of brush-backs is'going on, in accordance withftlie diagram shown in Fig. 4.

. It is obvious that the holes of one, two

or more brush-backs can be simultaneously drilled and filled by the same'machine, also that any desired size of brush-back within certain limits can be drilled and filled by the actuation of one and the'same pattern wheeland the adjustable lever-mechanisms by which the lateralreciprocating as well as the longitudinally-reciprocating motion of the table is controlled and adjusted for any desired size ofbrushes, so that thereby the scope of the machine is considerably en la-rged and the same better adapted for the manufacture of cloth, shoe, ha r, nail, scrubbing and other brushes.
